QARRIAeE-AXLE.

i SPECIFICATION forming part of Letters Patent No. 294,222, dated February 26, 1884.

Application led June 30, 1883. (No model.)

To all whom t may concern:

Be it known that I, JOHN GOWLAND, of Philipsburg, in the county of Centre and State of Pennsylvania, have invented a new and. useful Improvement in Axles or Spindles; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in spindles or axles, and has special reference to that class of such devices wherein is provided means for a continuous lubrication of the wheels mounted on said spindles or axles.

The object of the invention is the construction of a device of the character described which will be simple, durable, and effective; and to that end the invention consists of the novel construction and arrangement of certain of the parts, and of the novel combination of such parts, all as will be hereinafter fully described, illustrated, and claimed.

For the better understanding of the invention, reference will be made to the accompanying drawings,which form part of this speci iication, and in which- Figure l isa side view of an axle provided with inyimprovements; Fig. 2, a section taken on line was, Fig. l; and Fig. 3, a view in detail of a collar or sleeve used to exclude dust or dirt from the oil-chamber.

Like letters refer to corresponding parts in each of the several views.

In the drawings, A represents a spindle or axle, which may be made of malleable or wrought iron, or of steel castings, as desired. To the outer ends of this spindle A is secured a hollow sleeve, B. This sleeve is secured to spindle A, either by means of a ring, a, shrunken thereon, or by pressure, or by means of a screw-thread, as shown in Fig. 2. It extends out a suflicient distance beyond the end of said spindle A to form an oilchamber, b. (Shown clearly in Fig. 2.) The sleeve B is, as shown, perforated at c c, the perforations c opening into oil-chamber b, thus allowing oil to pass from said chamber to the wheel to be mounted upon said sleeve. Theperforation c opens directly into a groove, c2, which is made in the outer end of the spindle, and which communicates with oil-chamber b. Oil passes from chamber b through groove o2 and through which is inserted a linchpin, d, which may be of any well-known and desired form.- An opening, c, is also formed in this solid portion of the sleeve, which opening is, however,

drilled only about half through the sleeve, and then communicates with the oil-chamber b, before referred to.

Passed aroundthe sleeve B and occupying a position between the wheel and the linchpin is a movable collar, D. This collar, which is clearly shown in Fig. 3, is provided with semicircular notches ff', arranged diametrically opposite to each other. These notches are of such a size that the linchpin will t closely therein when desired, as will be described.

At a point on the collar D, and about midway between the notches f j", is formed a raised portion, j, which is provided with a notch, j, similar in form and size to the notches f f.

When the parts are in position, and it is desired to fill the chamber b with oil, the colf lar D is revolved until the raised portion f2 is brought over the opening c, which communicates with said chamber. This brings the notches ff opposite to the linchpin, one end of said linchpin entering notch j' and the other entering notch f. Then the oilV has been supplied, and it is desired to close the openinge and exclude all dustor dirt from the oilchamber, the collar D is revolved until the position of notches f f with respect to the linchpin is changed-#5. c., the end of the linchpin which in the first instance entered notch f nowenters notch f, the same change oc` curring with respect to the end of the linchpin which rst entered notchf. In this way the raised portion f2 of collar D is moved from opening c, and said opening covered by aportion of said collar, and the ent-rance of dust or dirt into the oil-chamber is rendered impossible.

I am aware that grooved spindles and perforated sleeves are old, and therefore do not broadly claim the same 5 but What I claim as new therein, and that for which I desire to secure Letters Patent, is-
